[BioC] clone id to chromosome position

[Al Tango]

Not sure if this needs using Bioconductor.

To get the chromosome position(in bp, Build36) for a BAC clone, eg
'RP11-189K9', I was following this post:
http://article.gmane.org/gmane.science.biology.informatics.conductor/11360/match=bac+position

But I only got this table:
'ftp://ftp.ncbi.nih.gov/genomes/MapView/Homo_sapiens/objects/BUILD.36.1/initial_release/clone.q.gz'

(Here is the first several lines of the table:
#tax_idclone_id	 xref_idclone_name insert_accession	insert_gi strain

9606	CloneID:1		RP11-1006M13			
9606	CloneID:10		CTA-102N2			
9606	CloneID:100	CTA-124G2
)

from which I can identify the CloneID '230700' for 'RP11-189K9',
without any positional information;
Where to go to get the additional dataset for positions, please?

Thanks a lot in advance for your reply. AT
